You thrive in early-stage startup environments where speed, ownership, and adaptability are critical. You dont just go along for the ride — you act as a driver, not a passenger, taking initiative and shaping outcomes rather than waiting for direction.

• Youre passionate about leveraging software and data to create meaningful impact, and you see the opportunity to contribute directly to decarbonization and enterprise transformation. You approach challenges with creativity, rigor, and a growth mindset, and you want to be part of a small team where your contributions have outsized influence.

• This is a true full-stack role where youll build core product features, contribute to data infrastructure, and take ownership of systems from design through deployment.

• Youll collaborate closely with product and design, experiment rapidly, and help define best practices that will scale with us. Youll be at the center of key technical and strategic decisions as we scale.
